Using Nsight Graphics 2020.2 causes these warnings when starting my application:
[Debug][Warning][General]"loaderAddLayerProperties: C:\\Program Files\\NVIDIA Corporation\\Nsight Graphics 2020.2.0\\target\\windows-desktop-nomad-x64\\VK_LAYER_NV_nomad_release_public_2020_2_0.json invalid layer manifest file version 1.2.0. May cause errors."

Not a real problem but annoying.
Note that the current max version for validation layers is 1.1.2.
